Dev Preview Blocks Localhost Subdomains Used in Multi-Tenant Local Development
Integrated preview tools block navigation to localhost subdomains like playground.localhost even though they resolve to the same loopback address. Multi-tenant applications that rely on subdomain routing cannot be tested through the integrated preview without workarounds. The restriction breaks local development workflows for a common SaaS architecture pattern.

Similar Problems
surfaced semanticallyClaude Cowork Desktop Unusable in Corporate Environments Without Proxy
The Claude Cowork desktop app runs in an isolated VM with no awareness of host-system proxy configuration, causing all API calls to fail silently in corporate networks behind HTTP/HTTPS proxies. Unlike Claude Code CLI which supports standard proxy environment variables, Cowork provides no mechanism to configure or inherit proxy settings, completely blocking enterprise adoption.
Plugin Dir Cannot Override Managed Plugins for Local Development
A managed plugin system does not allow local development overrides for mandated plugins. Teams using centrally managed settings cannot test local plugin changes without disabling the managed version.
Tailscale Exit Node Routing Breaks Local Docker Service Access
Developers running Tailscale with an exit node on their work machine lose access to locally bound Docker services (e.g., PostgreSQL on 127.0.0.1) because Tailscale's exit node routing intercepts all traffic, including localhost. The issue affects developers who need simultaneous VPN-routed outbound traffic and local container networking. A configuration flag (--exit-node-allow-lan-access) exists as a partial workaround, suggesting this is more a documentation/UX gap than a missing product category.
Reverse Proxies Lack Per-Service TLS Toggle for Self-Hosted Apps
Self-hosters running internal services like Proxmox or Kasm need to skip TLS verification on a per-service basis when using self-signed certificates on a LAN. Current reverse proxy tooling requires global static configuration, forcing users to choose between a blanket insecure setting or manual static file edits for each service.
